To all whom it may concern:

Be .it known that I, FRANCIS D. Tron, a

`citizen ofthe United States, and resident of Niantic, in the county ofNew London `and State of Connecticut, have invented certain new anduseful Improvements in Pumps, of which the following is a speci yof acycloidal or gyratory character.

While my invention is particularly adapted i for employment as a pump inwhich the gyratory motion of the piston is produced by a rotary motionof the shaft, 1t will be adapted for employment as an. engine, propelled by steam or gases or fluids, in which the gyratory motion ofthepiston will produce a rotary motion of the shaft.

The object of my invention is to reduce a mechanism of the classdescribe ,which will be extremely simple in construction, positive andeffective in operation, and which will produce an enhanced or maxi mumdegree of power with relation `to the units off operative forceemployed.

A further object of my improvements is to )rovide a `mechanism of theclass de scri ed 'which will possess general advantages in point ofsimplicity, strength and durability, inexpensiveness in construction,minimum friction, economy, and eiiiciency.`

In the drawings- Figure 1 is a vertical transverse sectional view of themechanism embodying my improvements.

Fig. 2 is a horizontal transverse sectional view thereof.

Fig. 3 is a verticalcross-section, taken on the line :1i-fm, Fig. 1.'

Fig. #L is aver-tical cross-section', taken on the line ,a-y, Fig. 1. l

Figs. 5, G, 7 and 8 are diagrammatic views, indicating differentpositions of the piston. Corresponding parts-in all the figures aredenoted by the same reference characters.

lieten-ring to the drawings, 1 designates. the main body creasing of themechanism, whch'isfmounted or fixed in any'suitable manner, preferablyvertical (for4 instance, upon a'base portion- 2), and-is interiorlyprovided with an annular chamber, 3, which constitutes the cylinder.rl`he body or casing 1 may be constructed in a single piece,

comprising an end wall, 4, forming the closed side' of the annularcylinder-chamber 3, a side wall, 5, forming the outer annular wall' ofythe chamber 3, and a centrallyarranged interior wall,as at 6,projecting from the end wall 1 and forming the .inner annular wall ofthe chamber 3. Beyond the cylinder-chamber 3, the main casing 1 isprovided with a chamber or interior space, 7, extending across thechamber Band Venlarged laterally with respect thereto, so that the fulldiameter of the chamber or'space 7 is greater than the full diameter ofthe cylinder-chamber 3, which clianfiber or space 7 accommodates thehead-plate ,of the pis-I ton in its operative movement. Said chamber orspace 7 may be formed by a flange extension or enlargement of the sidewall 5 of the casing 1, projecting from the same circumferentially, asshown at 8. The outer side of the chamber or space 7 is^c1osed by a sidewall, 9, oppositely located with relation to the end wall 4 of thecasing 1, which wall S) may consist of a cheek-p1ate,'as shown,removably secured,.by lbolts, as at 11, to the face of the flangeextension 8 which surrounds the chamber or s ace 7.

The cylinder-chamber 3 is divided by a fixed partition or head, 14,extending across the width of said chamber and preferably located at thetop4 thereof. At one side ozt' said partition, and immediately adjacentthereto, is located the exhaust port, 15, which is constituted by anopening in the end wall 4 which forms the closed side of thecylinder-chamber, from which openingmaysuitably extend an exhaust pipe,as

shown'at 1G. At the opposite side of said partition 14, and immediatelyadjacent thereto, is located theinlet port, 17, which is constituted byan opening 1n the -end wall `4 which forms theclosed side of thecylhitler-chamber, corresponding to theexha ust opening l5, and from theinlet port 17 may suitably extend a feed-pipe, as shown at 18. Thepiston comprises a plate or head, 19, operative in the chamber or space7 of the casing 1, having projecting from itsV inner face an annular orcircularaiiange,20,

'operative within Vthe cylinder-chamber 3.

vbeyond whichtlange the peripheral portion of said head 'or plate 19circumferentially extends, as at 2-1. The flange 20l1asii thickl ness"orWidth area less'than thel' width area ofthe cylinder-chamber, and it istransversely recessed, as ut 22, to receive the lxed partition or head14 in the chamber 25.

"lhe purpose of this: sprinL mounting inthe eeeentrie eonneetion between the slnift und the piston is 'to takeup un) deiid-ceuter resistance at the instant of the initiul starting;of the rotary movement of the Shaft und to iiirilitate the operativeaction be- 'tween the Shaft and the piston.

i 'partition or head 14 macero Fromthe foregoingnescription, it Will beunderstood that the disk-piece or block 37 is eccentrically keyed uponthe shaft 30 and operates eccentrically with relation to the piston, andthat the shaft is thus eccentrically mounted with relation to theoperation of the piston in the reverse gyratory movements of the latterwithin the cylinderchamber.

It Will be noted that the cheeklplate 9 operates to hold the piston toits seat and to yretain the disk-piece or block 37 in its eccentricmounting upon the shaft, and if desired a `suitable spring control `maybe interposed with relation to this maintenance of the operativeposition of the piston and said block. Itivill be further noted that theexhaust and inlet ports 15--17 extend, in the preferred construction,across substantially -tlie `complete Width area of the cylinder-chamber3.

The operation and-advantages of my i'nvention will be readily understoodby those skilled in the art to which itappertains. The piston has aneccentric movement vvith relation to the 20 has a reverse gyratorymovement in the cylinder-chamber and with relation to the as a fixedpoint, in

which movement the true center or axis of the piston with relation tothe annular flange 2() describes a movement in a segs mental path Withrelation to the axis of the shaft. The relative construction andopera-tion is such that at all times in the movement of the piston theinner face, 28, of the piston-flange 20 contacts at some point with theinner wall 6 of the cylinder- .chamber 3 and the outer' face, 29, ofsaid liange 20 contacts at some point with the outer wall 5 of thecylindenchamber. These contactsv `at all times during the movement ofthe piston cause the division, by the piston-flange 20, of' thecylinderchamber 3 into. two chambers, respectively operative as` inletand exhaust chambers,

during the movement and operation of the,

plston.

Then the mechanism pump, the shaft `30 lis driven and rotated by anysuitable source of-power and its eccentric 4bearing connection with the'piston causes the' operation of the latter in the reverse n gyratorymovement whereby the water entering at the' inlet port 17 Will bedischarged under pressure at the exhaust port 15. For an understandingof the operative movement and 'action of the piston, reference ,may behad to the diagrammatic illustrations' in `Figsl 5 to 8, inclusive. InFig. 5, assuming the piston to be at its lowermost point of movement,the inner face 28 0f the flange 20 is 4bevil-ing against the inner wall6 of the .cylinder-chamber 3 at the top and the outer face of said angeis hearing against the shaft and the 'piston-fiange is operative as a.

bottom, and the inlet and exhaust ports are respectively open to therespective spaces or outer wall of the cylinder-chamber at the chamberswhich then exist Within thecylin-` der-chamber, atopposite sides `of theparti# tion or head 14, between the pistonflange 20 and the outer wallchamber; now, as' the shaft 30 is revolved and.-.carries the pistontoward the position shown in Fig. 6, the Water in the chamber (indicatedat L) then at the righthand side of the partition 14 is driven by thepiston flange 20, in its direction Within the cylindenehamber, out atthe exhaust port, and the space or chamber at the left-hand side of thepartition 14 enlarges and fills with water from. the inlet port. Whenthe cylinder reaches the point shown in Fig. 6, the inner face 28 of thelane 20 is bearing avainst the inner Wall 6 of the cylinder-chamber 3 atthe left-hand side andthe outer face 29 of said flange 4is bearingagainst the outer Wall 5 of the cylinder-chamber at the right-hand side,and in this `position water enters from the inlet )ort to thechamber(indicated at-M) then. eginningto form at the left-hand side of thepartition 14 between the inner face 28 of the piston-flange 20and theinner wall 6 of the cylinder-chamber; now, as the piston continues,under action of the shaft, in the same direction of its eccentricmovement until it reaches its uppermost position, as shown in Fig. thewater in the chamber' L is entirely exhausted at the exhaust port, asuccessive chamber L is formed at the lower portion of thecylinder-chamber .between the outer face 29H01? the piston-flange 20 andthe outer Wall of the cylinder-chamber, and the chamber M enlarges andfills from the inlet port. When the piston has reached its `ppermostposition, as shown in Fig. 7, the outer face 29 of the Harige 2O isbearing against the outer Wall 5` of the cylinder-r chamber Sat the topand the inner face 28 of said flange, is bearing `again'sft"tlie innerWall 6 of the cylinder-chamber at the bottom; the

5 of the cylindereccentric movement in one l lor continued `rotation ofthe shaft in its opel-af K tionof the piston then reverses the eccentricmovement of the latter to a direction opposite to that it has describedin moving from its lowermost to its uppermost Which reverse eccentricmovement carries the piston toward the position shown in Fig. 8, and theWater in4 the chamber M is exhausted under pressure at the exhaust port.The reverse eccentric movement of the piston, as just described,Acontinues until the piston again reaches the lowermost "position, asshown in Figp, when the continued rotation of the shaft again starts thepiston in an eccentric movement in a reverse direction as hereinabovedescribed. 'It will be noted that,

during'the reverse eccentricmovements o'f position,

of the piston with relation to its annular flange 2O has described acomplete movement in the path of a circle about the axis ofthe shaft,and that the piston has reciprocated up and down upon the fixedpartition or head l-l at the top ofthe cylinder-chamber 3, the initialpoints of the respective reverse eccentric movements of the piston beingwhen the latter isat its lowerniost position (shown in Fig. 5) and atits uppermost position (shown in Fig. 7). It will further be notedthat-at all points iu the movement of' the piston and in the variablelocation ot' the respective chambers L and M into which thecylinder-chamber 3 is divided by the pistonlange'QO, water is alwaysentering the cylinder-chamber 3 at the inlet port at one side of thefixed partition or head ll and being forced out at the exhaust port atthe other side of said partition.

The extreme simplicity of the improved pump, under the constructionconstituting my invention as vherein described, is indicated by the.fact that the complete mechanism may consist in the main of but t'ourparts, to wit: the body or casing l (in which is formed thecylinder-chamber 3), the piston, the shaft. 30, and the movable' walltorniing the cheek-plate 9,-which respective four parts may .bepractically of4 integral construction.

1 do not desire to be understood as limiting myself to the detailconstruction and arrangement of parts as herein shown and described, asit is manifest that variations a'nd modifications therein may beresorted to, in the adaptation of my invention to varying conditions ofuse, without departing from the spirit and scope of my invention and improveniente. I` therefore'reserve the right to all such variationsandinodifications as properly fall within the scope of my invention andthe terms of the followingclainis.
